This paper proposes and presents a millimeter-wave (MMW) fundamental and subharmonic hybrid mixer in a 65-nm CMOS technology. Based on a hybrid structure with two switching quads and a quasi-diplexer, the proposed circuit can function either as a fundamental mixer (FM) or a subharmonic mixer (SHM) for dual-band applications. An application of the MMW hybrid mixer in a concurrent dual-band receiver is also discussed, which indicates that the proposed mixer can operate at two different MMW frequency bands concurrently as long as the frequency conversion schemes are carefully designed. Measured results show that the 3-dB RF bandwidth of the MMW hybrid mixer ranges from 16 to 35 GHz for the FM mode and 30 to 53 GHz for the SHM mode, respectively.

用于双频带应用的毫米波基波和次谐波混合 CMOS 混频器

本文提出并提出了一种采用 65-nm CMOS 技术的毫米波 (MMW) 基波和次谐波混合混频器。基于具有两个开关四通道和一个准双工器的混合结构，所提出的电路可以用作双频带应用的基波混频器 (FM) 或次谐波混频器 (SHM)。还讨论了MMW混合混频器在并发双频接收机中的应用，这表明只要仔细设计频率转换方案，所提出的混频器可以同时工作在两个不同的MMW频段。测量结果表明，MMW 混合混频器的 3-dB 射频带宽范围分别为 FM 模式的 16 至 35 GHz 和 SHM 模式的 30 至 53 GHz。
